series are designated as: x = U (U-channel), C(U-channel with Cover) or F(Cover with Internal fan).
Z = T(Terminal Strips) or M(Molex connectors).
＊
Ripple & noise measured from 10 kHz to 20 Mhz at output terminals with parallel 0.1µF ceramic and 22µF electrolytic capacitors.
＊
Providing peak power to 600W within 500 uS for all models, longer duty duration need contact manufacture in advance.
＊
1% minimum load is required to maintain the ripple and regulation.
＊
Output is fully isolated.
＊
Models provided with the optional cover (MPA350C), require 30 CFM forced air flow to achieve max rating.
